DEVICE FOR AUTOMATICALLY COATING YARN ELEMENTS FROM WHICH A LAMINATEDCOHESIVE INTERWOUND FABRIC IS CONSTRUCTED. I

To all whom i1 may con ern Be it known that l; LAWRENCE A. Somme, acitizen of the United States. and resident of East (.leveland, in thecounty of (javahoga and State of Ohio, have invented certain new anduseful improvements in Devices for Automatically Coating Yarn Elementsfrom \Yhich a Laminated (.lohesive Interwound Fabric is (."onstructed,of which I hereby declare the following to be a full. clear. and exactdescription, such as will enable others-skilled in the art to which itappertains to make and use the same.

This invention comprises an improvement upon the coating device of thema chine described in my previous application for Letters Patent bearingSer. No. (368,625 tiled December 30, 1911.. for-an automatically actingmaehine for laminated.cohesiveinterwound band in which the band elementsare coated under the influence of vacuum and heat and is also an im'irovement upon the automatically acting device "For coating the jarnelements from which a laminated-cohesive interwound fibrous band isconstructed, described in my application for Letters Patent hearing Ser.No. (378,696. tiled February 17, 1912, in which stationar guiding meansare employed acting! to hold the hand elements apart while being coated.ln both cases the band elements are stored upon reels which rotate inopposite directions. are wound about a stationary mandrel, are passedthrough a coating" device and finall) the completed hand is pulled fromthe man drel and compressed and dried under the action of vacuum andheat.

In the machine hereinafter described the several rotating reels haveattached thereto concentrie conical guide memhers which hold the severalseries of yarn elements and guide them in channels and-wind them uponthe mandrel in their exact relative positions. and also serve to holdapart the yarn elements while the coating material is applied thereto.The coating: chamber is separate and spaced "from the vacuum chamber.thus allowing the yarn elements to he coated in the air. thereby gaininga smooth uni'li'orm coating, free from bubbles. which are Specificationof Letters Fatent.

quickly formed when the yarn elements are coated in a vacuum chambersince the solvents are then quickly evaporated from the coatingmaterial.

'lurther object is to apply the coating: material preferably withoutpressure. to maintain it in asullieiently liuid state to permit ol themovement of the several series of yarn elements therethrough withoutdistortine them or without distortion of the yarns forming the elements.and to form a smooth outer coating on the band while still on themandrel.

A. further object is to wind the coated varn elements upon the mandrelunder as slight a tension as practicable so asto re duce the strain onthe hand in pulling it oil the mandrel since the greater the sion theharder the 'band is pressed against the pullingrolls thereby forcing outa cor-. responding greater amount of the, coating: material Further bywinding the series ol varn elements upon the iandrel without thereafterpassing: over an. enlarged expanding portion a large amount ()l frictionof the yarn ele from theinterior of the band] mcnts one upon the otheris eliminated and no opportunity is allowed for individual arns tobecome distorted from their positions in their respective elements. i

i also employ an open coating chamber spaced from the vacuum chamberinto which and over the rotating yarn elements the fluid rubber lowseither by gravity or by piessure and from which it is with drawn asouicltlv as desired.

The invention also includes resilient closin means for the severalapertures in the Zcoatinfi and vacuum chambers. and means priorapplication dll tlllil. tiled Feb. 2. 191%,.

Many portions of the machine previously shown and described in my formerapplicationreferred to, such as the pulling and flattening devices andband shaping devices are not shown again in this application since it isnot necessary to do more than to refer to them .her'ein. sincethey havebeen previously claimed.

In these views B is a stationary mandrel. B, B, B and BKare reelsrotatable in al-; ternately opposite directions thereabout.

C, C are rods secured to these reels and extending radially inward andprovided with guide rolls C, Q) for the bands of parallel yarns F, Fwhich compose the fabric band and are herein designated as yarnelements. Tension is supplied by tension rollers C and P and Springs 1for the yarn elements as they are pulled off from. the

spools C, (l. The inner ends of the rod C are provided with terminalguide rollers (.l, (3. Alternate reels rotate in opposite directions andthe rods from each reel, shown as four in number, are secured at theirlower ends to a ring F upon a frame F shown in Figs. 1 and 2. T be fourguide rods are secured to and equally spaced about this frame and therollers C pass the yarn elements F inside the ring F which forms thebase of the frame F. At the outer end of, this frame is shown a secondring F which is tightly sleeved over the reduced portion F of the guidering F This guide ring is provided with four guide channels F, F on itsouter face through which the yarn elementspass but they do not passdirectly therefrom to the mandrel B since the distance passed'overbefore winding them is too great to insure the accurate application'ofthe yarn elements thereto. For this reason 1 series of rings F F areprotided gradually nearing the surface of the mandrel so that the yarnelements wit! be accurately spaced apart and kept out of contact witheach other.

The rings F are provided with channels F, F alternately situated on theouter and inner sides of the rings so as to bind the yarn elements andprevent them from slipping or d'awing sidewise out of proper alinementand yet permitting them to be pulled freely off from the reels.

- In Figs. 1 and 3 the last one F of the series of channeled rings isreduced in diameter and is brought as close as possible to the mandrelso that the yarn elements can be applied thereto at as acute an anglewith the axis of the mandrel as may be desired, and the yarn elementsare bound. underneath in the channels F R therein, in close proximity tothe mandrel so that perfect'accuracy'in winding can be obtained withoutslipping, also the length of the yarn elements exposed between thechanneled guide and the surface of theniandrel is much reduced thereby.

Fig.3 is a perspective view of the outer-. most series of rings whichare connected together into a frame by means of longitudinal bars F FThe inner and larger ring is flattened and provided with transverseslots F F" and the bearing guide ring'F, is provided with correspondingpins F, F or other means of attachment so that the parts can bedetachably secured together and others substituted therefor if required.In this manner the guides are brought as near to the surface of themandrel as the angle of winding will permit and are spaced apart at a.predetermined distance. The several frames and guide rings attachedthereto are so ,proportioned and fitted together as to sleeve over eachother, space being left between them for packing rings F, F of felt orother soft material and are inserted in nest form into an opening F inone end of a coating chamber F which-opening they with the packing ringscompletely fill and prevent the. escape of rubber therefrom. The yarnelements fill the guide channels F and the rubber cannot escape. Therubber preferably falls by gravity through av funnel shaped spout F uponthe rotating guides and yarn elements and they are completely coatedbefore winding them on the mandrel.

The rubber or other adhesive material runs out of the outlet opening Fand the depth' of rubber maintained in the receptacle can be controlledat pleasure in any-"desired manner. The mandrel projects through anopening F" in the opposite wall of the receptacle and through an openingF in the wall F of the inclosed vacuum and heat chamber G. Theseopenings are preferably spaced apart so as to prevent any possibleaction of the vacuum upon the rubber in the guide elements therein.

, grates will tc-ml receptacle. The openings i l are protected byresilient gates formal of sliding sections F F controlled by one or moresprings F. These gates will make clo e contact with the fabric band asit passes out over the mandrel but will prevent the rubber from oozingout and will. yield sullicie ill; to permit a knot or collected mass ofrubber to pass. The resilient action of tl'iesc to smooth and equalizein thickness the exterior coating of rubber upon the fabric band.

in Fig. 5 is shown a central passage l and oblique passages F F in thennindrel through which the rubber can be injected into the interior ofthe fabric band before being; coll: psed to thoroughly coat the yarn. Anannular groove F communicating with these passages distrih utes therubber evenly around the exterior I of the mandrel.
